[3], In 1956 the second was defined in terms of the period of revolution of the Earth around the Sun for a particular epoch, because by then it had become recognized that the Earth's rotation on its own axis was not sufficiently uniform as a standard of time.

In scientific areas, seconds are often used for even large time measurements, with scientific notation applied in such cases. In practice, however, the definition means that high-precision realizations of the second should compensate for the effects of the ambient temperature (black-body radiation) within which atomic clocks operate and extrapolate accordingly to the value of the second as defined above. In physical science, time is defined as a measurement, or as what the clock face reads. [1] This definition refers to a caesium atom at rest at a temperature of 0 kelvins (−273.15 degrees Celsius; −459.67 degrees Fahrenheit) (absolute zero).

Second definition, next after the first; being the ordinal number for two. However, the Babylonians did not subdivide their time units sexagesimally (except for the day). The revised definition would seem to imply that the ideal atomic clock would contain a single caesium atom at rest emitting a single frequency. Following several years of work, Louis Essen from the National Physical Laboratory (Teddington, England) and William Markowitz from the United States Naval Observatory (USNO) determined the relationship between the hyperfine transition frequency of the caesium atom and the ephemeris second.
